Desktop Environment Integration
by Sean Allen 06 Apr '12

06 Apr '12

No right answer here. Just looking for information/advice about desktop environment integration. I've been using xmonad for about 16 months now and loving it. I currently use it integrated with gnome 2. About the only things I use gnome for are: gtk/desktop theming. easier multiple monitor setup. less x hassles. basically, has a shortcut to getting the basics configured. I'm going to be moving on from that machine soon and I'm trying to decide what to do. xmonad w/ nothing? <-- and handle all of the above issues manually gnome 2? gnome 3? kde? Problems using any of the above? Suggestions based on what I really care about with using gnome for best things to use? Seriously considering just going w/ xmonad but I really do like the little layer of 'not x' that I get with a gnome or kde or xfce etc. Thanks. -Sean-

Our current HCAR is at http://code.haskell.org/xmonad/man/HCAR.tex It was last updated for the 0.10 release. ---------- Forwarded message ---------- From: Janis Voigtlaender <hcar(a)haskell.org> Date: Wed, Apr 4, 2012 at 6:11 PM Subject: HCAR May 2012 To: Gwern Branwen <gwern0(a)gmail.com> [ASIDE: Please also consider submitting to http://www.haskell.org/haskell-symposium/2012/ !!!] Dear Gwern, I am currently planning the upcoming May 2012 edition of the Haskell Communities and Activities Report (HCAR). For a previous edition of HCAR, you have kindly provided material on the following topic: * xmonad I would very much like to receive an update from you on this topic for inclusion in the new edition. Your contribution is important to keep the report interesting and up-to-date, which in turn serves the entire Haskell community. The article from the previous report is attached to this mail. If you update it, please use the attachment as a basis. Completely new entries/topics are also welcome! If you want to include Haskell code, consider using lhs2tex syntax (http://people.cs.uu.nl/andres/lhs2tex/) The report is compiled in mode polycode.fmt. Please note that images (in .jpg format) are a good opportunity to pep up entries. If the attached .tex source does contain code for including images, please *do not change* that code (unless you want to drop the image in question, or add a new image, of course). In any case, please do not send me .zip archives or similar. Plain file attachements are the way. +++++++++++++++++++++++++++++++++++++++++++++++++++++ Please submit your entries until Tuesday, 1 May 2012. +++++++++++++++++++++++++++++++++++++++++++++++++++++ Thank you very much for your support.

how to install xmonad for group of users.
by Imam Toufique 04 Apr '12

04 Apr '12

Hi, I have been trying to install xmonad (using cabal) for the past week for a group of users and having some issues with it. When I try to install it for myself it works just fine, but I when I try install it for a group of users, it gives me errors that some packages/modules are missing. I used the following cabal command: >cabal install --prefix=$PREFIX --build-log=/tmp/xmonad.log.3 xmonad (where my prefix is /net/tools/xmonad/0.10 I see the installation there, I can run it myself, but when another user goes about it running it from the same installation, it complains that some packages/modules missing. I noticed that my installation creates $HOME/.ghc directory where all the packages are registered. I think therefore, for another user it can't access my $HOME/.ghc and therefore fails. Is there a way to tell cabal installer to register the packages in the $PREFIX area? I am so new to ghc, I tried figuring it out, but I could not. I think if I can register the packages somewhere in the PREFIX (/net/tools/xmonad/0.10) area, then xmonad running for a different user(s) will be able to access the right packages, and that might fix this issue. thanks in advance.

nedit-nc -tabbed no longer working
by Ben Franksen 04 Apr '12

04 Apr '12

Hi Xmonadists I am a long-time fan of the -- unfortunately no longer maintained -- text editor that goes by the name of 'nedit'. Nedit is built on the Motif toolkit. Nedit can be run in client mode (the executable is named 'nc' in this case, for nedit client, on debian and some other systems called 'nedit-nc') meaning that it attaches to a running instance of nedit. If given the extra switch -tabbed, it will open another tab inside an already open nedit server session. Depending on a configuration setting, it starts a new server if none is found. A few xmonad-versions ago 'nedit-nc -tabbed' suddenly stopped working. Instead of opening the file as a new tab inside the running session, a new window is opened. If no session is already running, I get _two_ windows, one with the file I specified (on the command line) and one with a new file ('untitled'), which is quite annoying, especially in a tiling wm such as xmonad. There is, by the way, only one nedit-server session running, so the client mode works in principle, only the -tabbed mode is broken. This works fine under all other window managers I tried, including those of gnome, kde, xfce, and lxde. I tried anything I could think of to fix possible problems with my configuration but to no avail. I gave up then and went back to using kde when programming. But I am missing xmonad very much and would really like to go back to using it, so I finally decided to report this as a bug. I think the nedit client mode utilizes some X11 feature for communicating between processes over the X11 protocol, but I have no intimate knowledge of X11, so I can't tell for sure. BTW, most linux distributions still offer nedit as a package, if yours does not the latest sources (from 2005) are available from the nedit.org site. I would be extremely happy and thankful if someone finds a solution for this problem so I could again use my favourite window manager *and* my favourite text editor together. BTW, I am currently on a 64 bit amd running debian testing. Cheers Ben

Retrieving screen resolution + ghci for XMonad
by Nicolas Dudebout 02 Apr '12

02 Apr '12

Hi, I am trying to align a dzen2 bar to the right of my screen. A dzen2 bar is aligned by giving an offset from the left side of the screen. Since I have a single xmonad.hs for multiple computers, I would like to retrieve the width of the screen from XMonad. I found the following snippet online: main = do (_, out, _, process_handle) <- runInteractiveCommand "echo WIDTH | eval m4 `xrdb -symbols`" ... This does not seem really satisfactory. I know this information is available from inside XMonad, probably in a ScreenDetail from XMonad.Core. My question is: "How can I retrieve this number from XMonad?" Another way look at that the question is: "What is the best way to figure out things in XMonad?" I have a specific question, found a potential candidate in the documentation, and would like to experiment before changing my xmonad.hs. Is there a way to use ghci to look around? Thanks.
